Consider this. If you are miserable then the shorter you live the better since you will suffer less. I learned from my mother's mistakes. She was a chain smoker and hated being alive her whole adult life. Maybe I would be too if I was addictted to nicotine. She died at 46 from a stroke and she finally got what she wanted. Note she was too proud to commit suicide and be remembered as a coward who could not deal with life. Personally I believe she would be a very happy person if she was not addicted to a narcotic.
